Effects of metabolic syndrome on the functional outcomes of corticosteroid injection for De Quervain tenosynovitis.

Metabolic syndrome is a constellation of medical conditions that arise from insulin resistance and abnormal adipose deposition and function. In patients with metabolic syndrome and De Quervain tenosynovitis this might affect the outcome of treatment by local corticosteroid injection. A total of 64 consecutive patients with De Quervain tenosynovitis and metabolic syndrome treated with corticosteroid injection were age- and sex-matched with 64 control patients without metabolic syndrome. The response to treatment, including visual analogue scale score for pain, objective findings consistent with De Quervain tenosynovitis (tenderness at first dorsal compartment, Finkelstein test result), and Disability of the Arm, Shoulder, and Hand score were assessed at 6, 12, and 24 weeks follow-up. Treatment failure was defined as persistence of symptoms or surgical intervention. Prior to treatment, patients with metabolic syndrome had mean initial pain visual analogue scale and Disability of the Arm, Shoulder, and Hand scores similar to those in the control group. The proportion of treatment failure in the metabolic syndrome group (43%) was significantly higher than that in the control group (20%) at 6 months follow-up. The pain visual analogue scale scores in the metabolic syndrome group were higher than the scores in the control group at the 12- and 24-week follow-ups. The Disability of the Arm, Shoulder, and Hand scores of the metabolic syndrome group were higher (more severe symptoms) than those of the control group at the 12- and 24-week follow-ups. Although considerable improvements in symptom severity and hand function will likely occur in patients with metabolic syndrome, corticosteroid injection for De Quervain tenosynovitis is not as effective in these patients compared with age- and sex-matched controls in terms of functional outcomes and treatment failure. LEVEL OF EVIDENCE: III.

Effect of metabolic syndrome on the outcome of corticosteroid injection for carpal tunnel syndrome.

Diffuse peripheral nerve impairment is common in metabolic syndrome: in patients with metabolic syndrome and carpal tunnel syndrome this might affect the outcome of treatment by local corticosteroid injection. A total of 55 consecutive patients with carpal tunnel syndrome and metabolic syndrome treated with corticosteroid injection (10 mg triamcinolone acetonide) were age and sex matched with 55 control patients without metabolic syndrome. Grip strength, perception of touch with Semmes-Weinstein monofilaments and Boston Carpal Tunnel Questionnaires were assessed at the baseline and at 6, 12 and 24 weeks follow-up. The two groups had similar pre-operative grip strength and Boston Carpal Tunnel Questionnaire scores. The Boston Carpal Tunnel Questionnaire symptom and function scores of the metabolic syndrome group were significantly greater than the control group at 12 and 24 weeks follow-up. Except for significantly greater grip strength at the 12-week follow-up in the control group, there were no significant differences in grip strength between the groups. Semmes-Weinstein monofilament sensory index for the control group was significantly greater than that of the metabolic syndrome group throughout the 24-week follow-up. After 24 weeks, five patients (13%) in the control group and 13 patients (27%) in the metabolic syndrome group had had carpal tunnel surgery. Patients with metabolic syndrome are at risk for poor functional outcome and failure of treatment after corticosteroid injection for carpal tunnel syndrome. LEVEL OF EVIDENCE: Treatment benefits III.

Clinical significance of skip lymph node metastasis in gastric cancer patients.

PURPOSE: Given the recent increase in the incidence of early gastric cancer, there is greater interest in identifying a minimally invasive therapy. The purpose of this study was to analyze the patterns of lymph node metastasis in patients with gastric cancer and to elucidate the clinical significance of skip metastasis. METHODS: We retrospectively analyzed patterns of lymph node metastasis (LNM) and clinicopathologic factors related to skip metastasis. RESULTS: Among 2963 patients with gastric cancer, 997 patients (33.6%) were detected as having LNM, and 27 patients (2.7%) with skip metastasis were detected among 997 patients with LNM. Skip metastasis were detected more frequently in the elderly. Compared with the N1 group, the skip metastasis group showed lower frequency of vascular invasion, and compared with the stepwise N2 group, the skip metastasis group showed smaller tumor size and a significantly higher incidence of negative lymphatic, vascular, and perineural invasion. CONCLUSIONS: Currently there is no way to predict N2 station LNM including skip metastasis, D2 LN dissection for gastric cancer is thought to be the appropriate treatment, even during early stage disease. Minimally invasive therapy should be performed cautiously in consideration of possible skip metastasis.

MicroRNA-29c functions as a tumor suppressor by direct targeting oncogenic SIRT1 in hepatocellular carcinoma.

Mammalian sirtuin 1 (SIRT1) has connected to an ever widening circle of activities that encompass cellular stress resistance, energy metabolism and tumorigenesis. However, underlying mechanisms leading to oncogenic SIRT1 overexpression are less understood. In this study, we identified SIRT1 regulatory microRNA (miRNA) and its function in hepatocellular carcinoma (HCC). Aberrant SIRT1 overexpression was demonstrated in a subset of human HCCs. SIRT1 knockdown suppressed HCC cell growth by transcriptional deregulation of cell cycle proteins. This led to hypophosphorylation of pRb, which inactivated E2F/DP1 target gene transcription, and thereby caused significant increase of HCC cells to remain in the G1/S phase. A comprehensive miRNA profiling analysis indentified five putative endogenous miRNAs that are significantly downregulated in HCC. Ectopic expression of miRNA mimics evidenced miR-29c to suppress SIRT1 in HCC cells. Notably, ectopic miR-29c expression repressed cancer cell growth and proliferation, and it recapitulated SIRT1 knockdown effects in HCC cells. In addition, miR-29c expression was downregulated in a large cohort of HCC patients, and low expression of miR-29c was significantly associated with poor prognosis of HCC patients. Taken together, we demonstrated that miR-29c suppresses oncogenic SIRT1 by way of binding to 3'-untranslated region of SIRT1 mRNA causing translational inhibition in liver cancer cells. The loss or suppression of miR-29c may cause aberrant SIRT1 overexpression and promotes liver tumorigenesis. Overall, we suggest that miR-29c functions as a tumor suppressor by regulating abnormal SIRT1 activity in liver.

Predictive factors for lymph node metastasis in patients with poorly differentiated early gastric cancer.

BACKGROUND: Endoscopic submucosal dissection is gaining popularity in the treatment of early gastric cancer. This study aimed to identify clinicopathological factors predictive of lymph node metastasis in patients with the poorly differentiated early gastric cancer to assess the feasibility of using endoscopic submucosal dissection for these cancers. METHODS: The records of patients with poorly differentiated early gastric cancer who had undergone gastric cancer surgery between January 2002 and December 2009 were reviewed. Associations between clinicopathological factors and the presence of lymph node metastasis were analysed by univariable and multivariable logistic regression analysis. RESULTS: Some 1005 patients were included in the analysis. Univariable analysis indicated that lymph node metastasis was associated with sex, ulceration, tumour size, depth of invasion, macroscopic type, lymphatic invasion and venous invasion. Logistic regression revealed that lymph node metastasis was significantly associated with sex, tumour size, depth of tumour invasion and lymphatic involvement. In the group with none of these risk factors (men with mucosal tumour no larger than 2 cm in size, with no lymphatic involvement), lymph node metastasis was present in four (3·2 per cent) of 124 patients. CONCLUSION: In the present study 3·2 per cent of patients who were negative for all identified risk factors had lymph node metastasis. The use of endoscopic submucosal dissection should be considered carefully in the treatment of poorly differentiated early gastric cancer.

Surgical outcome after incomplete endoscopic submucosal dissection of gastric cancer.

BACKGROUND: Endoscopic resection of early gastric cancer is a relatively new and attractive treatment, but occasionally fails to remove all cancer lesions completely. This study aimed to elucidate clinicopathological factors that could be helpful in predicting residual tumour in the surgical specimen after incomplete endoscopic submucosal dissection (ESD). METHODS: Patients who underwent gastrectomy because of incomplete ESD between August 2004 and August 2008 were analysed. Clinicopathological characteristics were reviewed retrospectively from prospectively collected medical records. Patients were classified into groups with and without residual tumour. Pathology results following gastrectomy were compared with those of incomplete ESD. RESULTS: A total of 118 patients were included. The incidence of residual tumour in the surgical specimen was 24·6 per cent after incomplete ESD. Elevated/flat-type cancers, large tumours (at least 2 cm) and those limited to the mucosa had significantly higher incomplete ESD rates. Cancer limited to the mucosa and the presence of tumour in the lateral margin were associated with residual tumour in the surgical specimen (both P = 0·001). CONCLUSION: Radical gastrectomy should be performed if pathological examination reveals a positive lateral resection margin after ESD.

Low frequency mutation of the Ephrin receptor A3 gene in hepatocellular carcinoma.

EphA3 is a component of the Eph/ephrin tyrosine kinase system, which participates in vasculature development. This receptor/ligand system is associated with various signaling pathways related to cell growth and viability, cytoskeletal organization, cell migration, and anti-apoptosis. Accumulated evidence suggests that aberrant regulation of EphA3 and its genetic alterations are implicated in the development and progression of various cancers. However, despite a high incidence of EphA3 over-expression, no such investigation has been performed in hepatocellular carcinoma. Thus, we investigated genetic alterations of the EphA3 gene in 73 cases of hepatocellular carcinoma by single-strand conformational polymorphism and sequencing. One novel D219V missense mutation was found in the extracellular domain of EphA3, and two genetic alterations in the intracellular sterile-alpha-motif (SAM) domain of EphA3 appeared to be polymorphisms. Although the functional assessments of this mutant are incomplete, it is believed that this novel EphA3 mutation may contribute to the development of hepatocellular carcinoma.

Decreased expression of p12 is associated with more advanced tumor invasion in human gastric cancer tissues.

BACKGROUND/AIMS: p12(DOC-1) is a well-known growth suppressor; however, its role in gastric carcinogenesis is still unclear. We investigated the expression of p12(DOC-1) in gastric cancer tissues and its possible correlation with p53 expression, and determined its clinical significance. METHODS: Immunohistochemical staining using the tissue array method was performed on 180 human gastric carcinomas. The clinicopathological features and prognostic significance were analyzed. RESULTS: Of the 180 tissue samples, p53 expression was positive in 85 (47.2%) and p12(DOC-1) expression was negative in 140 (77.8%). The negative expression of p12(DOC-1) was significantly associated with a more advanced depth of tumor invasion and stage (p < 0.05). No apparent correlation was found between p12(DOC-1) and p53 expressions. The 5-year survival rate of the p12(DOC-1)-positive cases (53.7%) was higher than that of the p12(DOC-1)-negative cases (39.3%); however, neither p12(DOC-1) nor p53 expression status had any statistically significant prognostic value. Multivariate analysis revealed that lymph node metastasis, distant metastasis, lymphatic invasion and perineural invasion were independent prognostic factors. CONCLUSIONS: This is the first report that suggests that p12(DOC-1) may be involved in the development and progression of gastric cancer. Further studies are required to clarify its exact role in the mechanism of gastric carcinogenesis.

Mutational analysis of JAK1 gene in human hepatocellular carcinoma.

UNLABELLED: The Janus kinase 1 (JAK1) gene encodes a cytoplasmic tyrosine kinase that is noncovalently associated with a variety of cytokine receptors and plays a nonredundant role in cell proliferation, survival, and differentiation. The mutated forms of JAK1 often altered the activation of JAK1 and then changed the activation of JAK1/STAT pathways, and this may contribute to cancer development and progression. Thus, to investigate whether genetic mutations of JAK1 gene are associated in hepatocellular carcinoma (HCC) progression, we analyzed genetic alterations of JAK1 gene in 84 human HCCs by single-strand conformational polymorphism (SSCP) and direct sequencing. Of 24 exons of JAK1 gene, 12 exons were previously reported to have mutations, we searched genetic alteration of JAK1 in these exons. Overall, one missense mutation (1.2%) was found. In addition, 12 cases (14%) were found to have single nucleotide polymorphism (14%) in exon 14. Taken together, we found one novel missense mutation of JAK1 gene in hepatocellular carcinomas with some polymorphisms. Although the functional assessment of this novel mutant remains to be completed, JAK1 mutation may contribute to the tumor development in liver cancer. KEYWORDS: JAK1 gene, hepatocellular carcinoma, mutation.

Employment status and work-related difficulties in stomach cancer survivors compared with the general population.

Little was known about work situation and work-related difficulties, including housework after stomach cancer diagnosis. We aimed to compare employment status and work-related difficulties between stomach cancer survivors and the general population. We enrolled 408 stomach cancer survivors from two hospitals 28 months after diagnosis and 994 representative volunteers from the general population from 15 geographic districts. Working was defined as being employed (including self-employed) and nonworking as being retired or a homemaker. Nonworking was significantly higher among stomach cancer survivors (46.6%) than in the general population (36.5%). Compared with the general population, the survivors had more fatigue in performing both housework (adjusted odds ratio (aOR)=2.08; 95% confidence interval (95% CI)=1.01-4.29) and gainful work (aOR=4.02; 2.55-6.33). More cancer survivors had reduced working hours (aOR=1.42; 95% CI=4.60-28.35) and reduced work-related ability (aOR=6.11; 95% CI=3.64-10.27) than did the general population. The association of nonworking with older age and being female was significantly more positive for survivors than for the general population. Among survivors, poorer Eastern Cooperation Oncology Group Performance Status and receiving total gastrectomy were positively associated with nonworking. Stomach cancer survivors experienced more difficulties in both housework and gainful employment than did the general population. Our findings on stomach cancer survivors' work-related difficulties and the predictors of nonworking will help physicians guide patients towards more realistic postsurgical employment plans.

Indication for endoscopic mucosal resection in early signet ring cell gastric cancer.

BACKGROUND: The aim of this study was to compare the clinicopathological characteristics of an early signet ring cell carcinoma (SRC) with an early undifferentiated carcinoma (mucinous, poorly differentiated adenocarcinoma) and early differentiated carcinoma (well or moderately differentiated tubular adenocarcinoma, papillary adenocarcinoma) and find indications for endoscopic mucosal resection (EMR) in early SRC. METHODS: 1520 patients with early gastric cancer (EGC), who underwent a curative gastrectomy, were analyzed retrospectively. Among them, 388 patients with SRC were compared with 253 patients with undifferentiated carcinoma (UDC) and 879 with a differentiated carcinoma (DC). RESULTS: SRC was more common in young female patients than UDC. SRC had a tendency to be confined to the mucosa, with smaller size than UDC. The lymph node metastasis rate for SRC was lower than that for UDC, but similar to that of DC. Multivariate analysis revealed lymph node metastasis (LNM) to be associated with the depth of invasion, tumor size, histological type, and lymphatic involvement. SRC had no LNM in the case of a mucosal tumor, smaller than 2 cm, and in the absence of lymphatic involvement. The prognosis of SRC was more favorable than UDC. CONCLUSIONS: Early SRC has different characteristics from early UDC. In view of the lower rate of lymph node metastasis and better prognosis, we suggest that EMR can be performed on patients with early SRC limited to the mucosa, less than 2cm in size, and with no lymphatic involvement.

Healthy twin birth after autologous islet transplantation in a pancreatectomized patient due to a benign tumor.

OBJECTIVE: Autologous islet transplantation has been reported to show favorable outcomes on glucose metabolism. The objective of this study was to describe successful delivery of twins in an islet recipient who had undergone distal pancreatectomy. PATIENT: A 35-year-old woman who underwent distal pancreatectomy owing to a solid pseudopapillary neoplasm received an autologous islet transplantation (140,000 islet equivalents). After 2.5 years, she unexpectedly became pregnant. Cesarean section was performed at 35 weeks delivering male twins without complications. Plasma glucose and insulin levels, insulinogenic index, and hemoglobin A1c were measured from the preoperative to the postpartum state as the main outcome. RESULTS: The patient showed impaired glucose tolerance before pancreatectomy, but improved to a normal glucose tolerance after transplantation, maintaining euglycemia until pregnancy. Because her fasting glucose levels were within the normal range during pregnancy, fasting insulin represented insulin resistance. Her fasting insulin levels abruptly increased in the third trimester of pregnancy, but returned after delivery. Insulinogenic index increased over 1 year after transplantation, but gradually decreased thereafter. During pregnancy, it increased again, but could not compensate for the insulin resistance. Therefore, gestational diabetes mellitus developed: glucose homeostasis recovered to normal after delivery. CONCLUSIONS: The current report suggested a successful pregnancy after autologous islet transplantation that did not itself permanently deteriorate graft function.

Gastric GIST: a single institutional retrospective experience with surgical treatment for primary disease.

AIMS: Because gastric GISTs show variable clinical behavior, we reviewed our experience with primary gastric GISTs after surgical treatment and imatinib mesylate treatment for advanced disease. METHODS: Between December 1995 and December 2005, 111 patients who underwent surgical treatment for primary gastric GISTs were enrolled in this study. Patients were grouped according to the risk assessment classification, and clinicopathological features, tumor recurrence and patient survival were assessed. RESULTS: One patient was included in the very low risk group, 35 in the low risk group, 31 in the intermediate risk group and 44 in the high-risk group. All patients with very low, low and intermediate risk GISTs and 70% of patients with high risk GISTs underwent R0 resection. While there was no recurrence or metastasis in patients with very low, low and intermediate risk GISTs, 23% of those with high risk GISTs showed a distant metastasis at diagnosis and 35% of these patients had a recurrence after R0 resection. The overall 5-year survival rate of the high risk patients was 77.1%. Nineteen patients received imatinib mesylate therapy due to an incomplete resection or recurrence; 7 with no measurable lesion at the CT scan by a local tumor control showed no tumor progression after imatinib mesylate therapy, however, 12 patients with measurable lesions showed variable clinical courses after treatment. The overall 5-year survival rate of 19 patients with imatinib mesylate treatment was 80.0%. CONCLUSIONS: The clinical outcome of the very low, low and intermediate risk gastric GISTs was excellent, while high risk gastric GISTs had a high rate of recurrence and therefore a less favorable outcome. A complete resection is the most important treatment for cure; however imatinib mesylate treatment may improve the clinical outcome of the patients with metastatic or recurrent gastric GISTs.

Prognostic model to predict survival following first-line chemotherapy in patients with metastatic gastric adenocarcinoma.

BACKGROUND: This study was to devise a prognostic model for metastatic gastric cancer patients undergoing first-line chemotherapy. PATIENTS AND METHODS: A retrospective analysis was carried out on 1455 gastric cancer patients, who received first-line chemotherapy from September 1994 to February 2005. RESULTS: At multivariate level, poor prognostic factors were no previous gastrectomy [P = 0.003; relative risk (RR), 1.191; 95% confidence interval (CI) 1.061-1.338], albumin < 3.6 g/dl (P = or <0.001; RR, 1.245; 95% CI 1.106-1.402), alkaline phosphatase > 85 U/l (P = or <0.001; RR, 1.224; 95% CI 1.092-1.371), Eastern Cooperative Oncology Group performance status of two or more (P = or <0.001; RR, 1.690; 95% CI 1.458-1.959), the presence of bone metastases (P = 0.001; RR, 1.460; 95% CI 1.616-1.836), and the presence of ascites (P = or < 0.001; RR, 1.452; 95% CI 1.295-1.628). Of 1434 patients, 489 patients (34.1%) were categorized as low-risk group (zero to one factors), 889 patients (62.0%) as intermediate-risk group (two to four factors), and 56 patients (3.9%) as high-risk group (five to six factors). Median survival durations for low, intermediate, and high-risk groups were 12.5 months, 7.0 months, and 2.7 months, respectively. CONCLUSIONS: This model should facilitate the individual patient risk stratification and thus, more appropriate therapies for each metastatic gastric cancer patient.

Primary malignant retroperitoneal tumors: analysis of a single institutional experience.

AIMS: In order to achieve complete resection in the surgical management of retroperitoneal tumors, it is crucial to know the tumor's anatomical location relative to neighboring organs. METHODS: Forty-nine patients with primary malignant retroperitoneal tumors were divided by tumor location into two groups [upper abdomen (group 1) or lower abdomen (group 2)], and clinicopathological features, tumor recurrence, and patient survival were assessed. RESULTS: No significant differences in preoperative clinical characteristics existed between two groups, and liposarcoma was the most frequently observed tumor type. The difference in the rates of complete resection between the two groups was not statistically significant (75.9% for group 1 and 85% for group 2). En-bloc combined resection was performed in 52% and 30% of patients in groups 1 and 2, respectively. The local recurrence rate in group 2 (31.3%) was higher than that in group 1 (9.5%), despite the fact that the differences in rates of complete resection and distant recurrence rates (14.3% in group 1 and 12.5% in group 2) between the two groups were not statistically significant. The overall 5-year survival rates were 67.9% for group 1 and 43.2% for group 2 (p=0.038). The 5-year survival rate of patients with tumors smaller than 10 cm was 78.4%, while that of patients with tumors larger than 10 cm was 38.1% (p=0.017). The 5-year survival rate after complete excision was 61%, whereas that after incomplete resection or biopsy only was 40.0% (p<0.0001). CONCLUSIONS: An upper abdominal tumor location is a positive prognostic factor even if small tumor size (<10 cm) and complete resection of the tumor are still more important factors to improve outcome in patients with malignant primary retroperitoneal tumors. Because complete resection was shown to be the most important prognostic factor, an aggressive and careful surgical approach is recommended for the treatment of such tumors.

Characteristics of submucosal gastric carcinoma with lymph node metastatic disease.

AIM: To study the correlation between lymph node metastatic disease and various pathological parameters. Lymph node metastasis is the most important factor in determining the prognosis of patients with early gastric cancer and is significantly associated with the submucosal invasion of neoplastic cells. However, the depth of submucosal layer as well as the depth of submucosal tumour invasion varies among different cases. METHODS AND RESULTS: We studied various pathological parameters including the macroscopic appearance, location, size, area, differentiation, invasion depth, vascularity and fibrosis of submucosal gastric carcinomas (SMGC), using 248 age- and sex-matched tissue samples. The presence of lymphatic emboli, a larger area, greater size, a non-flat gross type and an increased vascularity of the tumour were significantly associated with node-positive SMGC. Among the three depth-related parameters, the ocular scale measurement, the sm3 method and the sm2 method, only the ocular scale measurement showed a significant correlation with node-positive SMGC. Using multivariate analysis, the incidence of lymph node metastasis increased in the lymphatic tumour emboli and in the tumours that invaded more than half of the submucosal layer. CONCLUSIONS: These histological indicators seem to be a feasible and easy way to predict lymph node metastatic disease from limited surgery specimens. Pathologists should carefully investigate the lymphatic invasion of tumour cells and measure the invasion depth of the tumour.

Patterns of failure in gastric carcinoma after D2 gastrectomy and chemoradiotherapy: a radiation oncologist's view.

The risk of locoregional recurrence in resected gastric adenocarcinoma is high, but the benefit of adjuvant treatment remains controversial. In particular, after extended lymph node dissection, the role of radiotherapy is questionable. Since 1995, we started a clinical protocol of adjuvant chemoradiotherapy after D2 gastrectomy and analysed the patterns of failure for 291 patients. Adjuvant chemotherapy consisted of five cycles of fluorouracil and leucovorin, and concurrent radiotherapy was given with 4500 cGy from the second cycle of chemotherapy. With a median follow-up of 48 months, 114 patients (39%) showed any type of failure, and the local and regional failures were seen in 7% (20 out of 291) and 12% (35 out of 291), respectively. When the recurrent site was analysed with respect to the radiation field, in-field recurrence was 16% and represented 35% of all recurrences. Our results suggest that adjuvant chemoradiotherapy has a potential effect on reducing locoregional recurrence. Moreover, low locoregional recurrence rates could give a clue as to which subset of patients could be helped by radiotherapy after D2 gastrectomy. However, in order to draw a conclusion on the role of adjuvant radiotherapy, a randomised study is needed.

Postoperative chemoradiotherapy for gastric cancer.

BACKGROUND: We report the results of postoperative chemoradiotherapy after curative resection in gastric cancer patients. PATIENTS AND METHODS: Patients with gastric cancer staged IB to IV(M0) were treated with chemoradiotherapy after curative resection with extensive (D2) lymph node dissection. Nodal metastases were observed in 261 (90%) patients. The chemotherapy consisted of fluorouracil 400 mg/m(2) plus leucovorin 20 mg/m(2) for 5 days, followed by 4500 cGy of radiotherapy for 5 weeks with fluorouracil and leucovorin on the first 4 days and the last 3 days of radiotherapy. Two 5-day cycles of chemotherapy were given 4 weeks after the completion of radiotherapy. RESULTS: Of 290 patients accrued, 229 (79%) patients completed chemoradiotherapy as planned. With a median follow-up of 49 months, 114 (34%) patients have relapsed: 33 (29%) locoregional relapses, 76 (67%) peritoneal relapses and 41 (36%) distant metastases. The 5-year overall and relapse-free survivals were 60% and 57%, respectively. Tolerance was acceptable, the main toxicity being neutropenia. CONCLUSIONS: This postoperative chemoradiotherapy after curative resection of gastric cancer was feasible, with acceptable toxicities. Whether this adjuvant therapy in gastric cancer patients that have undergone a D2 lymph node dissection impacts on survival or reduces the incidence of relapses remains to be studied.
